Introduction was made to the formation mechanism, characteristics and the inlfuence of transformer inrush current on trans-former’s differential protection. Analysis was made to the principle and process of inrush current control technique based on phase controlled breaking-closing technique. Experiments were conducted in the dynamic simulation system. The results show that this method could accu-rately realize the inrush current control relatively, improving the accuracy and efifciency of test on transformer’s differential protection.
